Features of double girder overhead crane with hoist trolley

• The crane bridge's double girder structure provides sufficient strength, rigidity, and stability.
• The rail-in-middle box girder design satisfies the requirements for strength, rigidity, and stability.
• Simple-structured end beams can be easily installed with the main beam of the double girder crane by using high-strength bolts.
• As for the lifting mechanism, a high quality CD or MD wire rope electric hoist is used, which also can be designed with your lifting retirements.
• Soft starting motors with low current are used in conjunction with ground overhead crane control.
• A dual-motor independent drive device is used to reduce rail gnawing wear and the possibility of wheel climb off track faults. etc.
• The motor is directly controlled by a contactor, which allows for single and double speed control as well as reversing.
• A frequency converter is used to change the frequency and voltage of motor power in order to realize the function of motor speed control.
• A multi-level safety protection system is used, which includes short circuit protection, no-voltage protection, emergency power off switch protection, overload limit protection, travel limit protection, zero and chain protection, ground protection, and other features.
